Hello, We are planning on buying several swiss travel passes before the sale ends on March 31. This is the problem.....our daughter has to change her name on her passport. Her new passport will not arrive until after the sale date. I'm not sure if her current passport number will change when she receives her new passport with the name change. Can I order the Travel Pass with her current passport number? What will happen if her new passport has a different number? Thank you so much!
